Nice. SVG, i see!

The mac style window-icons were annoying, given they didn't respond to hover and click as expected! :)

The starting left side panel that shows all the supported command is quite useful for someone that is learning. However, it's either blocked by the demo screen at the start. Or it would be cleared every time a tutorial is chosen, and it doesn't show up at all when ?NODEMO is added. I think you might want to move that to the right, or move the starting tutorial/demo screen to not block that panel.

I'd like to keep the 'show goal' window open but it obscures the prompt for me (FF20) so I have to keep reopening it. I might not make it very far before abandoning it.

wasn't this just on HN a few months ago?

In shorter word, it is because Github's domain change from .com to .io, so HN just treat that as a different uri.

FYI, this is unusable on an ipad running chrome.

If you're training git, you probably should be on a device meant to do development.

Nice resource for a newbie like me. I really liked the interactive command line. Playing with it.

I already learnt a lot, but could have done with more help, not always clear what is expected (rampup3) and no way to see the solution... i got stuck on rampup3 a bit frustrated

To see the solution, type: show solution

I didn't see that hint until the very last level but I think it should work for all of them.

It looks really cool but I'm on my phone and found it mostly unusable. (iPhone5,Chrome)

Nice job. Confirmed my impresstions that git is confusing as hell.

Most of this is about advanced git features, Simple features are simple (checkin/out, push/pull, simpler branching). Which is 80% of what you need, and probably 99% of what you need most of the time.

This is good fun...
